Responses to Previous Year Reviewers’Comments

• Clear definition between portions of budget directed toward codesetting bodies, . . ., etc., and that part . . . used specifically for R&D– R&D part (fuel quality, testing/validation, integrated engineering) are

separate subtasks in FY05– National/international templates, subcontracts to SDOs are separate

subtasks in FY05• Gather international input if available

– developing international template for standards and regulations– developing international collaboration on R&D for hydrogen safety,

codes and standards– member of US delegation to ISO TC197 plenary– member of US TAG to ISO TC197– working with JARI, FCTESTNET, HySafe, HyApproval, etc.

Hydrogen Safety

To date, no hydrogen hazards have been associated with this project as no laboratory or field work has been conducted. Fuel quality testing initiated at the University of Hawaii is funded under a different program.

Page 28: Hydrogen Codes and Standards · – Delineate key tasks, timetables, budgets – Build on JARI, ASTM, USFCC, SAE, CAFCP, U of Hawaii, FCTESTNET work – Incorporate into C&STT R&D

Hydrogen Safety

When fuel quality or other testing is initiated under this project, our approach to deal with hazards is to:• follow all provisions of the Guidance for Safety Aspects of

Proposed Hydrogen Projects issued by the DOE Hydrogen Safety Panel

• follow all relevant provisions contained in test protocols• follow all standard operating procedures established by the

institution conducting the tests

Future Work: Test Plan-Part 1

• Identify relationships between contaminant type/level and fuel cell material properties, considering:

– anode catalyst– membrane material– MEA assembly– contaminant species– fuel cell operating conditions

• Provide basis from which to better define H2 fuel quality– use in conjunction with vehicle system requirements (storage, BOP, etc.)– serve as guide for H2 fuel providers/suppliers

• Generate database from which alternative resolutions may result– alternate materials (MEA) that are contaminant ‘immune’– regenerative procedures (operational functions) for performance recovery

• Provide basis for international collaboration– address issues common to all PEM fuel cell vehicles– data to help guide DOE-funded activities

Specifically address vehicular PEM fuel cell performance issues affected by H2 fuel contaminants
